The DSC6003CE1A-080.0000 is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a fixed 80 MHz CMOS output with ±50 ppm absolute pull range. The 1.71V–3.63V supply range means it can run from a 1.8V or 3.3V rail without a separate regulator — useful for mixed-voltage designs where the core and I/O banks share a single oscillator.
Automotive-grade qualification and package fit
Obsolete — sourcing and replacement planning
For existing designs, last-time-buy quantities may be available through independent surplus channels — confirmed at RFQ. For new designs, a functionally equivalent MEMS oscillator from the same DSC60XX family with a different order code may serve, but the pinout and electrical ratings must be verified against the BOM.
